Title: Improved manufacture of electric resistances
IPC: H01C17/08
Filed: 1924-10-13
Abstract: 223,563. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Oct. 17,1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Resistance coatings and deposits.-A thin layer of conducting material is applied to an insulating material by volatilizing the conducting material in a vacuum and precipitating it on an insulating material arranged within the vacuum. As shown, a tungsten, carbon, molybdenum, platinum, or other filament 3 in an exhausted vessel 1 is heated by a current to such a temperature that it volatilizes slowly, forming a deposit on the inner wall of the tube. Metal rings 4, 5 are arranged against the inner wall of the tube and are connected to platinum or other leading-in wires 6, 7. The rings 4, 5 may be silvered, or may consist of platinum, gold, or silver mirrors burnt into the glass. The leading-in wires 6, 7 may consist of a nickel-iron core with a sheath of copper, in which case the wire may be fused round the interior of the tube 1, the rings 4, 5 being omitted. In order to obtain better contact with the rings 4, 5 or their equivalents the layer may be thicker at these points. For this purpose the inner wall of the tube 1 between the wires 6, 7 may be covered after a thin layer has been formed, and the volatilization of the wire 3 continued. In this case the vessel 1 is modified to permit the removal of the filament 3 so that a screen may be placed in position.

Title: A pneumatic thrust amplifier for gear boxes
IPC: F16H63/20
Filed: 1959-07-16
Abstract: 921,219. Fluid-pressure servomotor-control systems. FABBRICA ITALIANA MAGNETI MARELLI S.p.A. July 16, 1959 [July 16, 1958], No. 24490/59. Class 135. [Also in Group XXIV] In a power-assisted gear shift mechanism a shaft 26 is slid axially for gear selection by rotating a control-rod 10 and is rotated to establish a gear by a pneumatic servomotor on sliding the control-rod 10 axially. The rod 10 carries an arm 18 having a ball end 20 in a socket member 22 carried by an arm 24 of the shaft 26. On rotation of the rod 10 the shaft 26 is moved axially to bring a selected striker 42, 44, 46 carried by a stirrup 48 fast with the shafts into register with an associated fork 56, 58, 60 carried by shift-rods 50, 52, 54. On shifting the rod 10 axially the arm 18 engages a push-rod 70 or 71 actuating a valve 76 or 77 provided in a piston 64 to cut off a chamber C2 or C1 on either side of the piston from the atmosphere and open the chamber to pneumatic pressure. Play is provided in the socket member 22 to enable this to take place before the socket is moved by the ball 20. Movement of the piston 64 is transmitted by rollers 87 or 86 to the socket 22 to rotate the shaft 26 and engage the selected gear. Since the valves are mounted in the piston, the piston follows up the motion of the arm 18. If the servomotor is inoperative the shaft 26 is actuated directly when the play in the socket has been taken up. The control-rod 10 is retained in its axial positions by a spring-urged ball detent 14. The shaft 26 has recesses 36, 38, 40 which are respectively aligned with a selected shift-rod, the other rods being held stationary by full diameter portions of the shaft 26 engaging notches in these shift-rods.

A chamber 4 is provided between the two members 1, 2 pressurization thereof causing the members 1, 2 to move relatively to each other against the spring loading to relieve the force transmitting element 15 of at least part of the force exerted by the spring 5. The force transmitting element 15 is operatively connected to one of the members through a clutch which is engaged when the pressure in chamber 4 is below a predetermined value thereby to permit the spring 5 to apply a force to the element 15. Pressurization of the chamber 4 above the predetermined value disengages the clutch so that the element 15 can move freely in either direction relative to the one member 2. In the construction shown one part of the clutch comprises a nut 13 which cooperates with a clutch face 12 on the one member, i.e. a piston 2, and also with the element 15 through a reversible thread arrangement 14. The clutch is urged away from its engagement condition by a pressure responsive member 20 under the action of pressurized fluid in a chamber 37 fed from chamber 4 against the action of a spring 33. The clutch can be disengaged manually by rotating a hex. 51 which through its toothed co-operation with a member 40 threadedly connected to the piston 2 moves the pressure-responsive member 20 in the clutch disengaging direction. The hex. 51 is loaded to its rest position by a torsion spring 46. The element 15 is pivotally connected to a thrust member 26 which is, in turn pivotally connected to a brake arm 28. These applications of the spring force applying means (60) in brake linkages are disclosed in the Specification with reference to Figs. 2, 3 (not shown).

Title: Improvements in or relating to actuating means for dipping or tilting headlights formotor-vehicles and the like
IPC: B60Q1/064
Filed: 1925-10-03
Abstract: 263,920. Abell, G. H., Wells, R. G., and Fitzwilliam, W. C. de M. Wentworth-, (trading as Sheffield Simplex Co.). Oct. 3, 1925. Pistons. - A double-acting fluid pressure operated piston 6 in a cylinder 5 has a lost motion operative connection with the piston-rod 7, which is automatically locked in any position against movement other than that imparted to it by fluid pressure in the normal operation, the locking means being released during the relative movement of the parts permitted by the lost motion connection. The piston-rod 7 is secured to a double conical wedge 11 surrounded by a cage 18 having apertures 19 for accommodating pairs of balls 15, 16 with interposed springs 17. When the piston is moved by fluid pressure in one or other direction, the balls 15 or 16 are forced out of wedging engagement with the wedge 11 and the cylinder wall, after which the cage 18 engages and moves the wedge 11 and the piston-rod 7 until the cylinder 5 is disconnected from the pressure source when the balls 15, 16 are forced by the springs 17 into engagement with the wedge 11 and the cylinder wall to lock the piston-rod in the adjusted position. To preserve the wall of the cylinder 5 from damage, a thin split sleeve 32, movable with the cage 18, may be interposed between the balls 15, 16 and the cylinder, the balls being disposed opposite slits 33 in the sleeve. In a modification, the balls 15, 16 are adapted to engage cam faces 35 of segments 34, Fig. 6, instead of the cylinder. In other modifications, the wedge 11 may take the form of a double-conical wedge with the portion of largest diameter in the centre, and the balls may be replaced by rollers.
